The making of the “Golden Rathaus” Story and methods of a very specific 3D printed model

Abstract: The twentieth edition of a conference happens only every twenty years, so, for this event, a group of habitual participants to the activities of the “Cultural Heritage and New Technologies” conference, decided to organize a special surprise, preparing and realizing a “golden” version of the Wiener Rathaus building to show and to homage Wolfgang Börner as the main chairman of this well organized and pleasant yearly event. It has been a nice experience, both because of the various troubleshooting needed to pass from an existing model to a 3D print and because the not easy golden material effect. So the situations were so articulated and various that we decided to write down a paper about all the realization phases, to enrich and to transmit the final result and complete this particular occasion with a full description about the “making of” of the “Golden Rathaus”.
